'17@45/ v www@ @fr/@070111 Reissued Feb. 19, 1935 UNITED STATES PATENT .OFFICE TYPE SETTING MACHINE Clifton Chisholm, Cleveland, Ohio, assignor, by mesne assignments, to Multigraph Company, Wilmington, Del., a corporation of Delaware 80 Claims.

This invention relates to a keyboard operated typesetting machine, and is particularly concerned with such provisions of the mechanism as will enable the r-apid assemblage of short grooved type, such as used in the multigraph. Preferably the assemblage is made directly onto a channeled multigraph segment, which may thereafter be installed in a multigraph for printing in cooperation withA a suitable platen. Positiveness of operation and continuous control of the type from the time it leaves the case until it is mounted in the assemblage member is one of the objects of the invention.

Another object of the invention is to provide for printing a reproduction of the characters as they are being assembled, thus providing at once a guide to the operator and a proof of the assembled matter. In accomplishing this, I employ both as the printer and the keyboard for the typesetting machine, a standard typewriter which is so mounted and connected that its keys may be operated in the usual manner to print on paper on the carriage and at the same time effect the selection of a corresponding type in the case,

which is thereupon ejected and is added to a lineV of characters being formed.

One'of the features of my invention comprises arranging the selecting mechanism of the type setter which is operated by the typewriter in such manner that no positive connection of the typewriter is required. When the typewriter is put into place, it automatically comes into position with relation to the selecting mechanism, the keys of the typewriter operating by a push on the selecting mechanism to effect the vconjoint operation; but whenever desired the typewriter may be simply lifted off for use elsewhere by simply disconnecting the clamps which engage its frame.

A very valuable feature of my invention is the provision of means absolutely preventing the transposition of characters, no matter how rapid the keyboard may be operated. This is effected by automatically locking the keyboard and type selector against subsequent operation as soon as any key is depressed, and continuing such locking until after the ejected type is actually in the assembled line.

Ease of manual operation of the machine is also one of the features of the invention, and this I effect by constraining the selecting mechanism by power and provide triggers to be released by the typewriter keys, so that hardly any more work is required of the operator than that usual in manipulating the typewriter.

Another feature which aids in the continuous assemblage of the type, by reducing the frequency of replenishment of type channels, is the provision of multiple channels for the most frequently used characters, especially the space quads, and shift mechanism associated with the key relating to such character to enable the operator to change instantly from one channel to another when the former channel becomes empty.

Other features of the invention, contributing to the eiciency of the complete operation, will be apparent from the following detailed descrip.- tion of an embodiment of the invention, the essential novel features of which are summarized in the claims.

Brieiiy, as illustrated in Figs. 1, 2 and 3, my typesetting machine lcomprises several -correlated instrumentalities, to which, I have apportioned reference numerals as follows:

1st. A standard* typewriter covered by reference numerals 1 `to 99, which include the supporting frame;

2nd. An upright. duplex .type case having channels apportioned to the diierent type characters equipped with ejecting plungers, to 199;

3rd. Normallyr constrained mechanism released by the keys of the typewriter -for selecting the type-ejecting plungers 200 to 299; f

4th. Power operated mechanism released by the selecting mechanism for operating the selected plunger to eject type from the bottom of the Vtype case 300 to 399;

5th. Subsequently acting power mechanism for transferring the ejected type to add it to the line being vformed 400 tov 499;

6th. A multi-.channeled type holder 500 to 599 in which successive lines are assembled into a page form suitable for printing.;

7th. Certain manual controls-600 up.

The main frame of my complete machine includes a bed plate 1 which is supported on suitable legs 2. The frame 11 of the typewriter is supported bythe bed 1 preferably by means of standards 3 rising from the bed. The typewriter frame may be clamped to the bed by any suitable typewriter clamp not shown. The key lever mechanism of the typewriter, however, simply has a push connection with the typesetter mechanism, enabling the typewriter to be readily lifted oi when its frame is released.

The typewriter machine may be of any suitable form, preferably one of the existing standard machines, and, as shown, comprises the frame 11, paper carriage 12, platen roller 13 carried thereby, finger keys 14, key levers 15, type bars 16 operated by the key levers to print on paper against the platen. Each type bar has upper and lower case characters 17 and 18, se-

lected by movement of the carriage by a shift key as later explained. The inking ribbon of the typewriter and various other parts are omitted from the drawings, as they will be well understood. Y

The type case in which the type isstored, comprises a series of parallel upright rails 101 and 102 with overhanging edges and suitable cross members 103 and 104 near the top of the rails, and 105 and 106 near the bottom thereof, secured to the backs of therails. These rails are preferably I-shaped in cross section, as illustrated in Fig. 27, and they occupy grooves in the cross plates, the base iiange of the rails seating in such grooves, a nd the metal of the plate being peened over thevrail base. I thus provide a pair 'of rigid multi-channeled upright members having their channels undercut, whereby they are adapted to confine type grooved on its opposite sides, such `type being of the character illustrated at A, Figs.

22 to 27 inclusive.

The cross barsl 105 and 106 to which the vertical rails or" the type case are secured extend crosswise of the machine and are secured at their ends to angle brackets 107 which in turn are securedto vertical plates 108 and 109 which are secured to the frame plate. The vertical plates also carry the cross bar 110 which forms the vbase for the channels, the support for the plungers, and provides the intermediate ledge or runway 111 onto which the -type are ejected.

One of the type banks for instance the forward bank 101 is designed tc carry lower case type and the other bank (102) carry the corresponding type of the upper case. The type in both banks face forwardly. The type descend by gravity te the lower end of their cases from which the bottcmmost type of the channel may be ejected by mechanism reieased by the lcorresponding key in the typewriter. The type is ejected from the front bank 101 rearwardly and from the rear bank 102 forwardly, so that in either case they come onto the intermediate ledge. `As the typewriter is provided with a shift key, enabling each key lever to print either of two characters,.1 provide shift mechanism for the type case, coupled with the typewriter shift key, whereby lowery case characters on the typewriter serve to eject lower case characters on the type case, for example. This will be hereinafter explained.

Extending through the bottoms of the respective type cases, are plungers .1.20 and 121, one for each type channel, each plunger occupying a groove in the base barllO.V Plates 112 extending across the grooves outside of the type case proper, complete the guides for the plungers.

Each plunger or 121 is engaged by a correspending bell crank 122 or 123, the upper ends of which enter notches on the under-sides of the plungers, while the lower arms of the bell cranks furnish means by which they are operated as later explained. The corresponding front and back bell cranks are constrained toward each other by a light tension spring 125, which tends to keep the plungers in their innermost positions. Standing registration with the outer ends of the plungers, are a pair of universal cross rods and 131, mounted on spring arms 132 or 133, leading from rock shafts 134 or 135; When the machine is idle, the cross rods 130 and 131 bear 'against the outer ends of ali vthe plungers, but, when any bell crank isoperated toA withdraw the Cal til

rmounted in an oscillatable yoke 241.

plunger, that action carries back the corresponding cross rods.

As soon as a plunger is withdrawn, the bottommost type in the channel, which was resting on top of the plunger, will now drop in front of it. The side ribs of the rails of the type case terminate a distance above the plate somewhat greater than the thickness of a type, so that when a type drops in front of a plunger, it is released from the rails which had occupied its grooves; also the webs of the base bar 110, which stand between the plungers, terminate short of the type case rails, so that the type in front of the withdrawn plunger is free from lateral conf finement. Thereafter suitable mechanism, to be described, rocks the shaft 134 or 135, forcing the withdrawn plunger into the type case and ejecting the bottommcst type into the intermediate runway 111 between the cases.

I will now describe the mechanism by which the depressionv of a finger key of the typewriter operates to rock the corresponding bell crank 122 or 123, to withdraw a plunger, and also initiates the mechanism to operate the rock shaft 134 or 135 to return the withdrawn plunger.

Directly beneath each typewriter key lever 15, is a lever 201, pivoted at 202 on a standard 203, rising from a frame plate l of the machine. A suitable upwardextension 205 secured to this lever and having a shoulder directly under the key lever and close to it, causes the depression of the lever 201` whenever the key lever isA depressed. A tension spring 206, acting on the rear end of each lever 201, tends to elevate the for- Ward end. The typewriter machine is customarily provided with springs 20 (Fig. 3) acting upwardly on each key lever and adjusted by screws 21. These springs are preferably left in the machine so that the springs 206 need be no stronger than sufficient to raise the levers 20'1, against a suitable stopping cross bar 208.

On each lever 201 is a dog 210 pivoted to the lever at 211 and normally held in the vertical position shown, as a spring 213 pressing a pin 214 on the dog against the underside of the lever 201. This dog normally overlies a pivoted latching trigger 220 on a lever 230, which is pivoted at 231 to a frame standard 232, and extends well to the rear of that pivot into position to operate the bell cranks 122 and 123. Suitable tension springs 234 of considerable force connected to the rear portion of the lever, tends to elevate that portion and vlower the forward portion. Such lowering is prevented by the latch 220 engaging an abutment bar 222, a suitable spring 223 between the latch and lever 230 normally maintaining the latch in the position shown in Fig. 3. The latch 220, it will be understood, is an L-shaped or U-shaped piece of sheet metal, embracing the lever 230 and pivoted by the pin 225.

Now, when the key lever l5 of Fig. 3 is moved downwardly, lever 201 must move downwardly, thus causing the dog 210 to press downwardly on the trigger 220. This movement swings the trigger on its pivot 225 sufficiently to release it from the abutment bar 222, whereupon the spring 234 swings the llever 230 into the position shown in Fig. 4.

Each lever 230 extends beneath a corresponding pin 240, the set of pins being slidably If this yoke is in the position shown in Fig. 3, the pins will stand beneath the forward set of bell cranks 122, and hence elevation of thev rear end of the lever 230, consequent upon the actuation of the trigger by the ,depression of the typewriter key, will swing upwardly the horizontal arm of the corresponding crank 122, thus withdrawing the plunger 120. If, however, the yoke occupied a rearward position, as shown in Fig. 5, the movement of the same key would shove upwardly on the horizontal arm of the bell crank 123, thus withdrawing the plunger 121. The yoke 241 is `connected with the shift key of the typewriter.

Normally, the typewriter is operating with the lower case characters 18 on the type bars 16 and the yoke holds the pin 240, operating cn the `forward bell cranks which are associated with the lower case type case 101. When the typewriter shift brings the characters 17 into use, the yoke 241 is automatically shifted to bring the rear type case 102 into action.

The shift connection is best shown in Figs. 8 and 9. The yoke 241 is in the form of a bale pivoted at its ends 242 to the upright plates 108 and 109 at opposite ends of the type case. Secured to the bale is a link 245 leading forwardly to a bell crank 246 which has a lip 247 extending beneath the shift lever 30 of the typewriter. As

shown in Figs. 8 and 9, this shift lever is pivoted at 31 and has an upwardly extending arm 32 operating on a member 33 in the nature of a bell crank rigid with a cross` rod 34 on which rides a roller 35 carried by the typewriter carriage 12.

The usual position of the shift mechanism is that shown in Fig. 8, where the lower case characters 18 of the typewriter are in position to coact with the platen roller 13, and the pin yoke 241 is in the forward position. Now, when the shift key is depressed, its lever is rocked into the position shown in Fig. 9, which, through the mechanism stated, raises the typewriter carriage to bring the platen roller into position to coact with upper case characters 17, and at the same time rocks the pin frame 241 into the rear position, as shown also inFigs. 4 and 5.

It will be understood, of course, that the particular shift mechanism on the typewriter will vary with the make of typewriter employed, but for such shift mechanism to operate the setting machine, it is only necessary to arrange the bell crank 246 or its equivalent so that it will be engaged and operated by some movable part of the typewriter shift.

I provide mechanism preventing the depression of two keys at the same time. Such mechanism may readily comprise the well known expedient of a row of balls extending transversely across a set of levers in position so that any actuated lever must pass between an adjacent pair of balls, and there being only space enough in the whole train of balls for one lever. This is illustrated in Figs. 2, 3 and 35. As there shown, 260 indicates the balls and 251, 252 a container therefor shown as comprising a grooved overhanging bar and a retaining plate. The plate and bar are slotted in their upper portions for the passage of each key lever. Suitable abutment screws 265 at the ends of the ball raceway adjust their positie-n. f

The device just described is shown as carried by the frame 1, through suitable brackets, and as located directly beneath the forward ends of the levers 201. When any such lever is depressed, as indicated in one instance in Fig. 35, the aggregate space between the balls is appropriated so that no other lever may be depressed until such depressed lever has been returned. This effectively prevents the ejection of two type at a time;

it also prevents jamming of vthe typewriter type bars, by preventing two keys being depressed at once. Other mechanism hereinafter described 'operates automatically to lock the keyboard against actuation of a subsequent key immediately after a key has been depressed. This automatic locking takes effect substantially concurrently with the return of the key-operating lever from the train of balls, so that it is not within the manual capacities of the operator, in any normal operation of the machine, to depress a second key until after the machine has completed the operation initiated by the first key.

It will be understood from the description so far given, that whenever a key of the typewriter is depressed, it prints on paper on the carriage in the usual manner, and it also operates to the corresponding trigger to cause the withdrawal of the plunger from the corresponding type channel, and the moving back of the corresponding uni- Versal plunger operating bar. The additional manual work for the operator in releasing the triggers is insignificant, and such operation throws into action suitable power mechanism which completes the ejection and transfer of the type without requiring further work of the operator. Mechanism for accomplishing this will now be described.

In the particular embodiment illustrated, the power for the machine is derived from an electric motor 300 (Fig. 2) the armature shaft 301 of which carries a pulley 302 connected by a belt 303 with a pulley 304 which constitutes the loose member-of a single rotation clutch mounted on the shaft 310. Secured to the underside of the bed plate 1 of the machine are a pair of depending plates 311 and 312 (Fig. 12) suitably bracketed at their lower ends by a cross-rod 314. The shaft 310 is mounted in these vertical plates, and the clutch mechanism is mounted von the shaft between the plates.

The clutch is released by the action of any of the levers 230 which operate to raise a universal bar 250 extending across all of the levers. Ihe releasing of the clutch'gives a single rotation to the shaft 310 which, as presently explained, operates the rock shafts 134 and 135 to force inward any withdrawn plunger at the bottom of the type case, ejecting the bottommost type.

I will now describe the clutch and its immediately coacting parts as illustrated in Figs. 3Y and l to 16 inclusive. This mechanism includes a driving member 304 which is a pulley loose on thev shaft and carries an annular flange 305, which is shown as made separately and bolted to the face of the pulley; also a driven member 320, which is a collar keyed to the shaft 310 and extending within the flange 305, and has a periphery made up of several outwardly diverging portions, preferably by a short concentric portion 321, then a tangential portion 322, then an inward step 323 to the next concentric portion. The third member of the clutch comprises movable rollers 330 between the driving and driven member, and a retainer ring 331 positioning the rollers equi-distantly. The retainer 331 comprises a plate journalled on a reduced portion of the driven collar 320 and having an interrupted annular portion 332 which projects between successive rollers 330. The plate 331 is held in place against displacement by a plate 335 mounted on a hub portion 336 of the collar 320.

The plate 331 is provided with a radial shoulder 333 which rests normally on an abutment 340 controlled by the universal bar 250. A suitable Vend a pin 372.

tension 'spring 338 connects the plates 331 and 335' and is normally constrained when the shoulder 333 engages the abutment, which is the position illustrated in Fig. 15. This maintains the rollers on the concentric portions of the collar` 320, so that the latter is not driven.

' When the abutment is removed from the shoulder 333, the spring 338 reacts and shifts the disk 331 circumferentially with reference tothe collar 320 and thus carries the rollers 330 onto the tangential portions of the collar, binding the collar to the driving pulley 304 and giving a rotation to the shaft 310. Dur-ing that rotation, the abutment 340 will have been returned to normal position so that at the conclusion of the rotation the disk shoulder 330 will engage the abutment and s'top the movement of the shaft at the end of a complete rotation.

Keyed on the shaft 310 is a cam Ymember 350. This 'member has two disk cams nearly but not quite alike; that'isrto say, there isa cam 351 which is circular for over three-quarters of a circumference and then is flattened by a chord 352. The other cam 353 is circular for a slightly greater arcuate distance and is flattened'by a partial chord 354 similarly placed to the chord 352, but connected at one end to the arc by a cusp" 355. These cams rotate in the direction of the arrows in Figs. and 11, and the cam 353 releases its roller slightly later in the movement than the cam 351.

The cam 353 coacts with a roller 360 on a lever 361 which'is pivoted by a stud 363 to the depending frame plate 311. Beyond its lpivot the lever is connected by a link 365 with one of the bale arms 251 of the universal bar 250.

Normally, the flattened portions of thev cams 351 and 353 stand adjacent the cooperating rollers as illustratedin Figs. 10 and 11. In this position, the depression of any typewriter key results in rocking the lever 230, thereby raising the universal bar 250, and rocking the lever 361 which carries the clutch abutment 340 heretofore referred to. The result is that the roller 360 comes down in the recess of the cam 351 while the abutment 340 withdraws from the clutch shoulder 333 and the clutch is released. As the shaft 310 nowrrotates, the cam member 350 turns in the direction of the arrow. This raises the roller 360 as the concentricV portion of the cam comes beneath it. This rocks the abutment 340 back into potential position. It also pulls down the universal bar 250. This operates to restore the actuated lever 230. After such restoration is completed, the latch 220 is swung by its spring 223 to lbring its foot onto the seat provided by the recessed edge of the bar 222, relocking the lever.

The arms 251 of the universal bar 250 are rock Varms on a rock shaft 370 (Figs. 21 and 31). On this rock shaft is an arm 371 carrying at its free This pin extends into forks at the opposite ends of the rock arms 375 and 374 which are rigid on the rock shafts 134 and 135 which carry respectively the universal pusher bars 130 and 131.

It results from the above described mechanism that whenever the concentric portion of the cam 353 engages the roller 360, the universal pusher bars 130 and 131 are moved toward each other by power, and hence any withdrawn plunger 120 or 121 is shoved inwardly to eject the bottommost type onto-the zone between the two type cases on the surface of the cross bar 110. Mechanism to be shortly described then acts to advanc'e the ejected type toward the right' hand end of the machine, where the type are assembled into a line ready for delivery onto the multigraph segment.

The action of carrying the ejected type along the runway 111 is effected by the cam 351, the operation of which will now be described. This cam acts against a roller 380 on a lever 381 pivoted at 382, (Fig. 10) This lever carries at its free end a pin 383 engaging a slot in a lever 384 pivoted at 385. The roller 380 'may be given a tendency to move toward the cam by'a suitable spring 386 anchored to either lever 381 or vthe lever 384.

rThe lever 384 performs several functions simultaneously. One of the most important is to lock all the latches 220 on 'the levers 23o so that the typewriter cannot be again operated until the type setting operation initiated thereby is completed. This prevents the possibility of transporting type by operating the keys in very rapid succession. This locking mechanism is best shown in Figs.- 3, 4, 5 and 10 and will now be described.

To prevent the depression of a key lever of the typewriter during the cycle of movement of the clutch controlled cam, I provide a lock 390 which consists of a rocking plate projecting in the vicinity of the heels of the latch 220 operated by a rock arm 391. This arm is connected by a link 392 to the upper arm 393 of a bell crank which is pivoted to the frame at 394 and has a lower arm 395 connected by a link 396 with the lever 384 above referred to. The result is, that whenever the cam 351 has its concentric surface against the roller 380, the plate 390 is automatically swung upwardly behind the heels of all of the latches 220 as illustrated in Fig. 5, thus locking the latches and preventing operation of any key lever of the typewriter. f

I have -found that a convenient speed of rotation of the clutch is 350 revolutions per minute, and at such speed the cam moves the bar 390 to locking position in such `a small fraction of a second, that it isv physically impossible for the operator to depress a key in the minute theoretic interval between the release of the keys by the ball-lock andthe locking by the bar.

The second operation performed by the lever 384, when actuated by the cam 351, is to lock "down the universal bar 250. This is effected by the universal bar being engaged by the hooked upper end 387 of a` downwardly drawn link 386 connected to the lever 384.

A third operation of the lever 384 as actuated by the cam 351 is to operate mechanism shoving downwardly on any type arriving at the end of the horizontal runway 111. Thisis accomplished through a link connected to the free end of the lever 384, but the explanation will be'deferred until after the transferv of thetype has been described. y

Another operation performed by the single rotation shaft 310 is to shove the ejected type along the pathway 111 between the type cases.

This is effected by a crank 410, Figs. 3,710 and 12,

on the shaft 310 which has a pin 411 pivoted in a block 412 slidable in a slot 413 in an arm 414. This arm has a slidable pivot below the crank pin by means of a second slot 4 '15 in the arm embracing a fulcrum pin 417.

The fulcrum pin 4 17 isfixed' in use but adjustably positioned. To thisrend I make this pin a crank pin on the end of a crank 416 pivotally mounted on a stud 419, and I provide suitable means for locking this crank in adjusted position.

A convenient devceconsists of a pair of set screws 418, Fig. 30-, mounted in ears carried by the plate 312 and engaging opposite sides of the crank near the pin 417.

The upper end of the arm 414 carries a roller 420 (Figs. 10 and 12)' which operates in a horizontal groove 421 in a stationary bar 422 supported on posts 423 and 424 rising from thebed plate 1. The roller 421 is journalled on a screw 430 mounted in the arm 414. On the other side ci the arm a bushing 431 is mounted on this screw. This bushing is pivotally connected with a block 435 which-carries a horizontal bar 440 in line with the runway betweenv the type cases just above the fioor 110 therefor.

It results from the above vconstruction that the 'I upper end thereof totravel in a straight line.

The eifect of the movement of the'pusher bar 440 is to shove the type which was ejected toward the right of the machine. j v 1 To prevent jamming of the mechanism in case a type should for any reason foul, I connect the arm 414 with the block 435 in such manner that it is readily detachable therefrom. As shown in Fig. 10, the bushing 431 occupies an open notch 436 in the block 435, which notch is in eect normally closed by a plunger 437 pressed upwardly by a spring 438 mounted between ears on the block. Ordinarily, the connection acts as a usual pivot,l the pin rocking in its bearing, but in case there is any obstruction to the movement of the transfer bar 440, the pin 431 will simply pull out of the slot 436, camming down the l'plunger 437 in such movement.

When a type has been ejected, either rearwardly from the front bank of'type cases, or forwardly from the rear bank of type cases, it lies on its side on the support provided by the cross bar 110. Now, the clutch operated mechanism through the crank 410'and oscillating lever 414 just described operates to advance the push bar 449 along-this path. The forward end of this bar engages the'ejected type'and shoves it along the runway to a pointadjacent the right hand side of the type cases. v

The channel 111 alongwhich the bar 440 shoves the type A terminates at its right hand end in a vertical channel 4 70 which curves downwardly in a quadrant form. This channel is made to t the contour of the type sufficiently to guide it but loosely enough to allow it to drop freely, thus on opposite sides of the channel are curved ribs 471 and 472 (Figs. 17 and 26). The members supporting these ribs are cut away in front thereof to form rabbets for receiving the head of the type and are cut away to a somewhat less extent to the rear to form rabbets to receive the feet of the type.l Accordingly, as the plunger 44o is operated t' its extreme right hand position, the type A is shoved olf of fits support, and thence drops downward by gravity onto the curved chute, the rib 471 engaging one of the grooves'of the type and the rib 472 the other'groove.

As the typeY are veryV light, they are liable to become displaced, landI therefore provide means to true them up and `control the transfer along the horizontal channel to the downward. quadrant. v particular reference to inclusive. v y v i When the type are ejected forwardly from the Figs. 17, 18 and 22 to 26 These features `will now be described with rear case so that the plunger 121 engages the fiat foot of the type, the typeA is likely to stand in a true position, as shown in- Fig.` 2 5. Ilf, however, the type is ejected from the forward case rearwardly and if the character on the face of the type is at either side of the. center, one type is likely to stand askew, being tipped in one direction as shown in Fig. 22 or in the opposite direction as in Fig. 2,4, To rectify such skewed type, I form the end of the pusher bar 440 in apeculiar manner, that isA to say,Y it is provided with two separated shoulders 441 and 442 which are positioned to contact with the head and foot of the type when the latter is in true position as shown in Fig. 23, and beween these shoulders I provide a bevelled and rounded tongue 443 adapted to engage in the groove of the type. With such a shaped plunger if the type stands in the skewed position shown in Fig'. 22,v the, tongue coacting with the foot of the` type trucs it, bringing it into the position shown in Fig. 23; while if the type stands in the position shown in Fig. 24, the tongue coacting with the head also trues the type. If the type is already true as shown in Fig. 25, the tongue does 'not move, either the head or foot, but enters the groove idly until the shoulders 441 and 442. engage thQ hQ'd'- To prevent the type bouncing away from the pusher when it Strikes the type, I provide means to engage the upper surfaceof the type and bear down lightly thereon as thetype lies in the transfer channel. This channel is equi-distant from the front and rear columns of type and stands directlyheneath the. cross; bar .1.05. carrying the rails 101 ofthe forward type case. This type channel is surmounted directly by a bar 482 carried inA place, back` of the front rails 101 and beneath the bar 105. This bar 482 may be pressed dOw'nvar-.dlyV as a whole to. provide a. braking action in the type, on it, mayv carry individual detents to act in the type. The latter is thel form Shown in the drawings. l f

As shown in Figs,. 3, 17 and 1 8- the type restraining detents preferably` comprise a series of balls 480 located in a row over the type channel pressed downwardly by suitable springs 4 81 compressed by screws 483 all-mounted in the. bar482. Fig. 18 indicates a bottom plan of the bar 482,V and i-llustrates how the projecting portions vofr the balls coact with the type A, givingY it a tendency to remain in true position and prevent it being thrown` forward by the impact ofthe bar- 440'.-

On the underside of the bar 482 nearl the discharge end of the type channel, I provide aleaf spring 485 which is secured by suitable screws 486 or otherwise to the underside of the bar 482 and overhangsthe entrance to the channel 470 and presses the type-,downwardly when it comes off of its support. y

To prevent the possibility of the type sticking in the curved-channel4'10, I provide a periodically acting packer which moves downwardly a short distance at the upper end of the type channel for each type ejected, whereby such type is positively advanced into the channel. This packer comprises a suitable nger490 (Fig. 19) mounted on the forward end of an arm` 491 which is tight on a short shaft 492. This. shaft is journalled at its rear end in a suitable fra-me bracket 493 and at its forward end. it is journalled in an axial cavity in a normally stationary rock shaft 494. A radial pin 495, on thev shaft 492 occupying an arcuate slot 496 in ,the shaft 494 allows some independent movement of the two shafts. `A coil` spring 4957 surroupdingthe shaft 492 and anchored at one end to the frame standard 493 and at the other to the arm 491 tends to move the arm.

upwardly.

I have heretofore commented on the link connected to the end of the cam operated arm 384, (Fig. 10). This link is designated 498, pivoted at its upper end to an intermediately pivoted lever 494 which overhangs and limits the upwardv movement of the finger 470.

The normal position of the parts just described that illustrated in Figs. 10 and 17. In this position the finger 490 blocks the exit from the horizontal type channel. Now, as the cam 351 begins to act on its roller 380 (which is before the crank 410 has given much movement to the, arm 414 and the bar 440) the roller 380 is shoved upwardly, the link 498 is thereby pulled downwardly, and that part of the lever 499 (Figs. 2 and 17) engaging the nger- 490 is moved upwardly, whereupon the spring- 497 raises the finger above the entrance to the type channel 470. This position, is; maintained by the, concentricity of the cam 351 while the plunger 440 is shoving the type towardthe yright en d and over the top of the channel 479 and withdrawing thereafter. Then the flattened portion 352 ofj the cam comes-opposite the roller 380, and the latter isreturned by the spring 486', which is materially stronger than the spring 497, whereupon the 'link 498 is raised andthe member 499 comes down on the finger 490, thus positively shoving the type down into the channel.

The above described movement ofthe fingerk 470 is slight, being limited by the excess of the slot 496 over the pin 495. It is only suicient to advance the type a distance corresponding toits thickness. The type are thus automatically forcedk into the quad-rant channel one at a time as delivered from the type case. Then the type pass down this channel by gravity aligning with the previously formedportions of a line in the quadrant channel. I'he foremost type in such line stands on edge at the end of the quadrant channel as shown in- Fig. 17, so that the line is at all times ready for delivery into a suitable receiving channel, which is shown as a standard multigraph seg-ment, to be later described.

It will` be noticed that the actual discharge of individual type into the line channel 470 precedes the release of the keyboard lock heretofore described. The locking is continued after such transfer of the type until the pusher bar 440 has been returned by the crank and lever mechanism to a position beyond the type runway between the cases, so that it is impossible to operate a subsequent key lever either to eject type inadvertently or to cause-a plunger to force type against the` pusher bar. n

The discharge of the typel ntothe quadrant channel, and thesubsequent return to normal position of the nger 490 and the pusher bar 440 Y completes the operation of the clutch driven parts. As the clutch is. thrown out of action after rotation by the engagement of the clutch shoulder 333 with the abutment 410, it is desirable to provide some shock absorbing characteristic to theabutmentto reduce the sound and jar. To effect this, Ivmake the, abutment 340 on a block 450 which has a shank 451V slidably mounted in the lever 361. A compression spring 452 about this shank maintains it normally in the position` shown in Figs. 10andV 1,1, but lenables the y abutment to go. do-wn by theA engaging shoulder 333. against the action of the spring 452 at the moment of impact; after whichL the return of
